Answer:
The answer to your question is: y = 3x + 1
Step-by-step explanation:
Data
slope = m = 3
y-intercept = (0, 1)
Formula
(y - y1) = m(x - x1)
(y - 1) = 3(x - 0)
y - 1 = 3x
y = 3x + 1
1st number = x, 2nd number = y
Translating the question mathematically it becomes:
x-2 = 3y, or to make it easier: x= 3y+2, x+y= 22
Thus:
(3y + 2) + y = 22
4y + 2 = 22
Move the 2 on the other side, changing its sign to negative:
4y = 22 - 2
4y = 20
Divide by 4, to obtain only y:
4y : 4 = 20 : 4
y = 5
To obtain x:
x= (3*5) + 2= 15+2 = 17
Verify it: 17+5=22
Well, it says to use a calculator to calculate them. So a calculator I would highly recommend is the Desmos graphing calculator.

This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse.
The formula is
C^2 = A^2 + B^2
Both A and B are 90, so plugging them into the formula gives
C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200
So
C^2 = 16200
Take the square root of both sides
C = 127.2792
Round to the nearest tenth, giving
C = 127.3</span>
